Triethyl(trifluoromethyl)silane (TESCF3) can be used for fluoriantion of cyclic vinyl triflates with improved regioselectivities compared with other fluoride salts. It also can be employed for trifluoromethylation of aryl chlorides,trialkylsilylation reactions and deposition of perfluoro-methyl silica films.
